NY MAYOR BLOOMBERG HELPS LAUNCH NEW YORK HARBOR SIPHONS PROJECT |
| Press: |
Mayor Michael R. Bloomberg and Port Authority Executive Director Pat Foye on April 18 launched a $250 million construction project to boost economic development in New York Harbor. The project involves digging a new water transmission main – called a siphon – between Staten Island and Brooklyn that will allow for the removal of two existing tunnels that are currently at a much shallower depth. This will enable the dredging and deepening of the Anchorage Channel, a process that is critical to accommodate increased cargo volumes and larger vessels in future years. |

Seattle’s Tunnel Project Puts Construction Under Pressure |
| Press: |
At 200 feet deep, the pressure of the soil is equivalent to that of water at 165 feet deep or five times the earth’s atmosphere. At that depth, divers need to replace nitrogen with helium because the former starts to act like a narcotic, inducing a drunk-like effect.
It’s also the approximate maximum depth of the massive two-mile, 57.5-foot diameter tunnel construction crews are preparing to dig through the ground beneath Seattle to replace the Alaskan Way Viaduct – a project pushing the boundaries of technology while grazing the edge of extreme environments. |

Túnel Emisor Oriente: The biggest Sewage Project in the World |
| Press: |
In mid-2008 CONAGUA, the national water board in the Mexico Ministry for the Environment, embarked on the construction of the “Tnel Emisor Oriente”. With an internal diameter of 7 m, it will transport up to 150 m³ of sewage per second over a distance of 63 km beneath the capital and the federal region of Mexico towards the federal region of Hidalgo. The authorities and the population are convinced that the world’s biggest sewage project will reintroduce an element of quality to life in the city. |
